Example 1

As shown in fig. 1 to 4, the present utility model provides a technical solution: the utility model provides a prevent water conservancy drainage pipe of sewage backward flow, including drainage pipe 1, the inside fixedly connected with fixed ring board 3 of drainage pipe 1, one side fixedly connected with annular sealing plate 4 of fixed ring board 3, one side rotation of fixed ring board 3 is connected with two boards 5 that block water, one side of two boards 5 all fixedly connected with fixed block 13, the inside fixedly connected with fixed plate 8 of drainage pipe 1, the inside sliding connection of fixed plate 8 has movable rod 10, the one end fixedly connected with water conservancy diversion awl 9 of fixed ring board 3 is kept away from to movable rod 10, one side of board 5 that blocks water is provided with the linkage subassembly with the one end of movable rod 10, the linkage subassembly is used for driving the board 5 that blocks water and rotates.

With the above embodiment, when the water flow flows from left to right, the water blocking plate 5 is impacted and rotated, so that the water flow flows out of the drain pipe 1; when the inside backward flow that appears of drainage pipe 1, backward flow sewage can strike diversion cone 9 in advance to drive movable rod 10 and remove, and then drive the reverse rotation of board 5 that blocks water through the linkage subassembly, make its two boards 5 that block water laminate with annular closing plate 4 mutually, with this sewage backward flow that prevents, improve drainage pipe 1's practicality, make it be favorable to actual use more.

Example 2

As shown in fig. 1-4, one side of each of the two water blocking plates 5 is fixedly connected with a sealing strip 12, and one side far away from the fixed ring plate 3 is provided with an annular sealing groove 2 matched with the sealing strips 12. The water-blocking plate 5 is a semicircular plate structure. By arranging the annular sealing groove 2 and the sealing strip 12 which are matched with each other, when the water-blocking plate 5 is in close contact with the annular sealing plate 4, the sealing strip 12 can enter the annular sealing groove 2 and is closely attached to the annular sealing groove 2, so that the tightness between the water-blocking plate 5 and the annular sealing plate 4 is improved, and a water-blocking effect is achieved; meanwhile, the water blocking plate 5 with a semicircular plate structure is arranged, so that water can conveniently flow into the drainage pipeline 1 after impacting the water blocking plate 5.

Wherein, the one end fixedly connected with push pedal 11 that movable rod 10 is close to fixed ring board 3, one side fixedly connected with fixed block 13 of board 5 blocks water, rotates between push pedal 11 and the fixed block 13 and is connected with vaulting pole 6, and the outside of movable rod 10 just is located between push pedal 11 and the fixed plate 8 and overlaps there is spring 7. The linkage assembly is arranged to drain water flow and prevent water flow from flowing back.

Wherein, the inner wall of the drainage pipeline 1 is brushed with acrylic polyurethane coating, and the thickness of the acrylic polyurethane coating is forty to fifty millimeters. By brushing the acrylic polyurethane coating, the corrosion resistance of the inner wall of the drainage pipeline 1 is improved.
